I am running my rails application using the following
$script/server -d webrick
on my Ubuntu system , above command run the webrick s
i don't think it does if you use -d. I'd just kill the process.
In the future, just open up another terminal window instead and use the command without -d, it provides some really useful debugging output.
If this is production, use something like passenger or thin, so that they're easy to stop the processes or restart the servers
